Sheffield Corporation purchases a patent from Pharoah Company on January 1, 2020, for $75,000. The patent has a remaining legal life of 16 years. Sheffield feels the patent will be useful for 10 years. Assume that at January 1, 2022, the carrying amount of the patent on Sheffield's books is $60,000. In January, Sheffield spends $25,600 successfully defending a patent suit. Sheffield still feels the patent will be useful until the end of 2029.
